Description

Technical Field

[0001] This application generally relates to the field of new energy technology, and more specifically, to a lithium battery magnetic levitation conveyor line and a lithium battery packing system. Background Technology

[0002] With the increasing maturity of new energy technologies, lithium batteries are widely used in various industries, leading to a surge in market demand. The industry has invested heavily in automated production lines, but the capacity of existing lines still needs improvement. Common methods, such as using sliding rails or stacking more workstations, suffer from the problem of numerous, densely distributed workstations, requiring a large floor space. Furthermore, existing production lines suffer from long transfer times between workstations. Clamping and fixing at each workstation often requires the cooperation of fixtures and robotic arms, and transfer is also necessary after processing at each workstation, resulting in time-consuming and labor-intensive transfers. Solving the transfer problem has become a crucial issue in improving production capacity.

Detailed Implementation

[0035] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0036] See Figure 1In one embodiment, the magnetic levitation conveyor line 100 for the lithium battery 200 includes a magnetic levitation track, a levitated trolley 20, and a workstation device 30. The magnetic levitation track forms a loop structure, and the levitated trolley 20 moves along the magnetic levitation track under magnetic induction and can circulate within the magnetic levitation track. The workstation device 30 is arranged along the magnetic levitation track and is located on both sides of the magnetic levitation track. The lithium battery 200 is placed on the levitated trolley 20 for transport. Processing equipment can be installed on the workstation device 30. When the levitated trolley 20 moves to the workstation device 30, it stops at the workstation device 30 for a moment to allow the processing equipment to perform processing. After processing is completed, the levitated trolley 20 continues to move.

[0037] In this embodiment, the magnetic levitation track includes an upper track 40, a lower track 50, and a lifting connection device 10. The upper track 40 and the lower track 50 are arranged vertically. A lifting connection device 10 is provided at each end of the upper track 40. The lifting connection device 10 at either end can switch up and down, and the upper track 40 or the lower track 50 can be connected. The upper track 40, the lower track 50, and the lifting connection devices 10 at both ends together constitute a vertical return conveyor line. The upper track 40 uses a magnetic levitation line, and the lower track 50 uses a magnetic levitation line, or a hybrid belt conveyor line. The lifting connection device 10 includes a motor 11, a ferries 12, and a connecting track 13. The connecting track 13 is mounted on the ferries 12. The motor 11 drives the ferries 12 to move up and down, and the connecting track 13 can move up and down with the ferries 12. The connecting track 13 can connect to either the upper track 40 or the lower track 50.

[0038] See Figure 2 and Figure 3 In this embodiment, the levitating trolley 20 includes a base 25, a buffer mechanism 22, and grippers 21. The base 25, at least its base plate 251, is a permanent magnet for movement under magnetic induction. The base 25 may also include a placement platform 252 for placing the lithium battery 200, which is mounted in the center of the top surface of the base plate 251. A pair of grippers 21 are respectively located at the front and rear ends of the placement platform 252 along the conveying direction. The gripping surfaces 211 of the grippers 21 have protrusions 212 on their left and right sides, which grip the battery surface. At least one of the front and rear ends of the base 25 has a buffer mechanism 22, wherein one gripper 21 is connected to the buffer mechanism 22, or one gripper 21 is located on the buffer mechanism 22. Preferably, the buffer mechanism 22 is located at the upstream end of the levitating trolley 20. The upstream end refers to the end closer to the upstream direction along the conveying direction. Since a buffer mechanism is provided at the upstream end, while no buffer mechanism is provided at the downstream end, the downstream end is fixed as the reference end.

[0039] In this embodiment, the buffer mechanism 22 includes a buffer plate 222, a guide post 222, and an elastic element. The buffer plate 222 is fixed to the base 25. One end of the guide post 222 is fixed to the buffer plate 222, and the other end of the guide post 222 is movably inserted into the bottom of a gripper 21. The elastic element is located between the buffer plate 222 and the gripper 21 and is sleeved on the guide post 222. By setting the buffer structure, the opening and closing of the gripper 21 is controlled in a flexible manner, which can reduce the energy absorbed by the lithium battery 200 and release it slowly when subjected to impact, thereby reducing the instantaneous impact force on the lithium battery 200. The elastic element can be a helical spring, which is sleeved on the guide post 222. The guide post 222 can include multiple guide posts, for example, two guide posts 222, which are symmetrically arranged on the left and right sides of a gripper 21. Preferably, the base 25 is provided with a slide rail, and a gripper 21 is mounted on the slide rail in a way that allows it to move with the slide rail.

[0040] In this embodiment, the levitating vehicle 20 is provided with buffer heads 24 at both its front and rear ends. When adjacent levitating vehicles 20 collide, the buffer heads 24 abut against each other on the adjacent levitating vehicles 20, thus buffering the impact intensity. The buffer heads 24 can be made of silicone or can be made of magnets of the same polarity. The repulsive force between the two buffer heads 24 prevents the levitating vehicles 20 from colliding. It is understood that the magnitude of the repulsive force between the buffer heads 24 can be adjusted as needed.

[0041] In this embodiment, each gripper 21 has a limiting member 23 on at least one side, which is used to cooperate with the workstation device 30. Preferably, each gripper 21 has a limiting member 23 on both its left and right sides, and the limiting members 23 on each of the two grippers 21 can cooperate with a clamping mechanism 34 or an opening mechanism 33. The limiting member 23 includes a mounting shaft and a bearing, the mounting shaft is fixed to the side of the gripper 21, and the bearing is sleeved on the mounting shaft.

[0042] See Figures 4 to 9 In one embodiment, the workstation device 30 includes a workstation base 31, which is fixed to the frame of the conveyor line. The workstation device 30 is equipped with a clamping operating mechanism 33, which cooperates with a pair of grippers 21 to open or clamp the grippers 21. The clamping operating mechanism 33 includes a pair of operating blocks, each operating block corresponding to a limiting member 23. Depending on the application requirements, the operating blocks can be configured as support blocks 331 or clamping blocks 341, with one type of operating block provided on each workstation device 30.

[0043] The clamping operating mechanism 33 can move upward to cooperate with the limiting member 23, or it can move downward to disengage from the limiting member 23. Preferably, clamping operating mechanisms 33 are provided on both sides of the workstation base 31, symmetrically arranged to make the opening and closing of the suspended trolley 20 more stable. Preferably, the workstation base 31 includes a fixed plate 311 and a side plate 312. The fixed plate 311 is fixed to the frame, and the side plate 312 facing the magnetic levitation track has a lifting assembly 32. The clamping operating mechanism 33 is mounted on the lifting assembly 32 and moves up and down under the action of the lifting assembly 32. The lifting assembly 32 includes a driving component, a slide rail, and a slider. The slider is mounted on the slide rail in a vertical sliding manner. The driving component cooperates with the slider and can be a cylinder or a motor 11.

[0044] In this embodiment, the clamping operating mechanism 33 includes a vertical mounting plate 333, mounting blocks 332, and a pair of operating blocks. The vertical mounting plate 333 is mounted on a lifting assembly 32 on a workstation base 31. A mounting block 332 is provided at both the front and rear ends of the top of the vertical mounting plate 333 along the conveying direction, and an operating block is mounted on each mounting block 332. When the operating blocks are used for clamping, they are configured as clamping blocks 341. The clamping blocks 341 cooperate with the outer sides of the front and rear limit members 23 on the same side to clamp the limit members 23 in the opposite direction, thereby pushing the gripper 21 to move in the clamping direction. Preferably, the inner side of the clamping block 341 near the upstream end has a guide surface with a certain slope, which facilitates the movement of the bearing of the limit member 23 pressing against the guide surface, making it easier for the limit member 23 to be pushed in the clamping direction. A vertical surface is provided on the inner side of the clamping block 341 near the downstream side. The vertical surface can better resist the force that the suspended carriage 20 will continue to move downstream, and prevent the suspended carriage 20 from moving or swerving during the processing.

[0045] In this embodiment, when the operating block is used for the opening function, the operating block is configured as a support block 331. The support block 331 engages with the inner sides of the front and rear limit members 23 on the same side, respectively, to push the limit members 23 in opposite directions, thereby pushing the gripper 21 to move in the opening direction. Preferably, the outer side of the support block 331 near the upstream end has a guide surface with a certain slope, which facilitates the movement of the bearing of the limit member 23 pressing against the guide surface, and facilitates the limit member 23 being pushed to move in the opening direction. The outer side of the support block 331 near the downstream end has a vertical surface.

[0046] In one embodiment, a lithium battery coating system includes the aforementioned magnetic levitation conveyor line 100. Several processing devices are provided on both sides of the magnetic levitation conveyor line 100. The processing devices are adapted to the workstation device 30 so that the processing devices can process the lithium battery 200 on the workstation device 30 (e.g., cutting two-character processes, folding edges, attaching insulating sheets, etc.).
